2 Samuel 24:10

And David’s heart smote him after this numbering of the people: and David said to the Lord, I have sinned greatly in what I have done. Now therefore, O Lord, forgive, I beseech Thee, the iniquity of Thy servant, for I have acted very foolishly.

And the heart of David smote him after he had numbered the people; and David said to the Lord, I have sinned grievously, O Lord, in what I have now done: remove, I pray thee, the iniquity of thy servant, for I have been exceedingly foolish.
